Preferably, the inner diameter of the flow stabilizing pipe 1 is 40 mm-110 mm, and the flow stabilizing pipe with the inner diameter dimension can better ensure that the liquid in the flow stabilizing pipe is static and is not influenced by external disturbance or vibration, so that the liquid level height of the liquid to be measured can be accurately measured.
Specifically, a waveguide wire is arranged in the detection rod 3, a circuit part of the sensor excites a pulse current on the waveguide wire so that the waveguide wire generates a torsional wave pulse at the position of the floater 4, the current generates a pulse current magnetic field around the waveguide wire when propagating along the waveguide wire, and the floater 4 outside the detection rod 3 can move up and down along the detection rod 3 along with the change of the liquid level. A set of permanent magnet rings may be arranged inside the float 4. When the pulse current magnetic field meets the magnetic ring magnetic field generated by the floater 4, the magnetic field around the floater 4 is changed, so that the wave guide wire made of magnetostrictive material generates a torsional wave pulse (mechanical vibration wave) at the position of the floater 4, and the pulse (mechanical vibration wave) is transmitted back to the data processing module at a fixed speed. The position of the float 4, i.e. the position of the liquid level, can be determined accurately by calculating the time difference between the pulse current and the received torsional wave by means of the data processing module. Therefore, the effective measurement interval of the side wall of the flow stabilizing tube 1 is the height interval of the liquid level which can be detected by the detection rod 3. Further, the detecting rod 3 is insulated from the flow stabilizing tube 1. Preferably, the outer surface of the detection rod 3 may be provided with an insulating layer, and the insulating layer may be made of an insulating material such as plastic, ceramic, or glass.
